CLAPBOARD-MACH l N E.

SPECIFICATION forming part of Letters Patent No. 468,495, dated February9, 1 892. Application filed March 23, 1891. Serial No. 385,997. (Nomodel.)

To all whom it, may concern.-

Be it known that I, SUMNER L. INGALLS, a citizen of the United States,residing at Milford, in the county of Penobscot and State of Maine, haveinvented certain new and useful Improvements in Clapboard-Machines; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as willenable others skilled in theart to which it appertains to make and use the same.

My invention consists of an improved machine for sawing clapboards, andis illustrated in the accompanying drawing, which shows an isometricview.

The clapboard-machines in common use are all designed to saw roundbolts, cutting the wedge-shaped clapboards from the surface nearly tothe center of the boltand leavinga core, the bolt being dogged in theline of its central longitudinal axis.

My device is so constructed as that the bolt may be doggedfrom its upperedge, and admits of the use of small bolts, substantially one-half thesize of the bolts as now used, thus making possible the utilization ofmuch material now going to waste.

I provide a carriage A, of ordinary construction and traveling on tracksT, as commonly, with adjustable head-block B, moving lengthwise of saidframe and operated by Screw D, having crank d.

Upon the head-block B and the tail-block O of the carriage are brackets19 a, carrying dogs E E.

A shaft F is vertically projected through the head-block B and, turningin a bearing in said head-block, has its upper end supported in thebracket 1).

Upon the shaft F, above the head-block and underneath the dog E, a fixedspur-wheel G is mounted, and underneath said head-block upon said shaftis a fixed bevel-gear H. Similarly a shaft F is projected verticallythrough the tail-block O, and, turning in a bearing in C, has its upperend supported in the bracket 0.

Upon the shaft F, above the tail-block and underneath the' dog E and inline with the spur-wheel G, is mounted another fixed spurwheel G, whilebelow its bearing the shaft carries the fixed bevel-gear H and a ratchetwheel I.

gear H and is retained in position by the bracket 0. I

Upon some convenient portion of the bedframe of the machine is pivoted aspring-pawl P,-so located as to engage with one ofthe teeth of theratchet-wheel I as the carriageA moves backward. v

A circular saw S is vertically set and arbored in the machine-frame infront of the shaft K, as shown.

In operation the bolt is set in position for sawing and secured by thedogs E E from its upper edge, its lower edge being held by thespur-wheels G G. As the carriage A, carrying the bolt, moves forward, aWedge-shaped slab or clapboard is sawed off and the springpawl passesover the first tooth of the ratchetwheel I. As the carriage runs back, atooth of the ratchet-Wheel I engages with the pawl P and the shaft F isturned sufficiently to allow the pawl to pass the tooth of the ratchet.As the shaftF turns, it carries the spur-wheel G, and by means of thebeveled gears H and H, shaft K, and beveled gears M L operates the shaftF, carrying the spur-wheel G, which thus moves simultaneously andequally with the spur-wheel G, and the spur-wheels thus turn the bottomof the bolt forward. The amount of the turn is regulated by the positionand size of the teeth of the ratchetwheel I, which arose arranged as togive any required thickness of the wide edge of the clapboard. Theadjustable head-block B permits the sawing of bolts of various lengths,but is not essential where the bolts are of the same length, in whichcase a stationary headblock could of course be used as well.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is Y 1. The combination of a carriage traveling pastthe saw and having head andtail blocks, a shaft projecting verticallythrough and turning in the tail-block and carrying a fixed spurwheelabove said tail-block, a shaft projecting through and turning in saidhead-block and carrying a fixed spur-Wheel above said head-block, ageared connection between said shafts, a ratchet-Wheel upon saidfirst-named shaft, a spring-pawl so placed upon the machine or saw frameas to engage With said ratchet-wheel and turn said shafts and spur-Wheels during the backward movement of the carriage away from the saw,and devices for dogging the clapboard-bolt above said spurwheels.

2. The combination of a carriage traveling past the saw and having atail-block and an adj ustablehead-block, a shaft projecting verticallythrough and turning in the tail-block Witnesses:
